摘要：The Editors-in-Chief have retracted this article [1] because it shows significant overlap with an article by different authors that was simultaneously under consideration with another journal [2] and with a previously published article by another group of different authors [3]. In addition, the identity of the corresponding author could not be verified: Roskilde University confirmed that Beatriz Ychussie was never affiliated to this institution. The authors have not responded to any correspondence about this retraction.
